Descriptions

A certain Red Hat build of the pam_ssh_agent_auth module on Red Hat Enterprise Linux (RHEL) 6 and Fedora Rawhide calls the glibc error function instead of the error function in the OpenSSH codebase, which allows local users to obtain sensitive information from process memory or possibly gain privileges via crafted use of an application that relies on this module, as demonstrated by su and sudo.

Un determinado build de Red Hat del módulo pam_ssh_agent_auth en Red Hat Enterprise Linux (RHEL) 6 y Fedora Rawhide llama a la funcion de error en glibc en lugar de la función de error en el OpenSSH codebase, lo que permite a usuarios locales obtener información sensible desde la memoria de proceso o posiblemente ganar privilegios mediante la manipulación de una aplicación que confia en este módulo, como se demostró por su y sudo.
